My girlfriend had sex with her ex boyfriend dor the last time on august 2022 and she had unprotected sex with me for the first time on jan2024 and then again on august 2024 and at other times protected but we came to know that her ex boyfriend used to have paid sex with other girls and then I asked her to test for hiv and other stds she did hiv duo test 4th gen(ECLIA) on november 2024 and tridot test on december 2024 but on november 2024 I had some rash on my arms chest back and legs this rashes were pimple type and itchy not all over but few places so I tested for hiv after that om december 2024 with three tridot test and one hiv1 and hiv2 ab/ag with p24ag test (chemiluminiscence) all the test were negative then on March 2025 I did three hiv test put if which two were immunochromatohraphy these were also negative and one test on may 2025 retroquic test this was also negative but I am worried if she was already progressed to hiv or she has stronger immunity that why result are negative
